According to the BMA Medical Supplies Direct website, accessed 28/11/11, "The Omron M6 Comfort is a special comfort cuff version of the Omron M6. This unique pre-formed cuff is extremely easy to use and is more comfortable and easier to use than the regular soft cuff. It has a larger arm range of 22-42cm and is currently the top of the range home BP monitor with BHS validation". I've just received mine and found it very easy to set up and use. Will update this review in the future when I have had a chance to properly test it out but so far I have to say it looks excellent. Unlike the M10-IT, there is no facility to store readings for more than one person in the memory (although you can take readings without storing them so I guess you could use this for "guests" if you wanted to keep a "pure" record. Also no option to save to a computer but there is an included chart to manually record readings if desired. Personally, I think gimmick free and accurate is better anyway and I value the BHS validation highly. I also like the fact that it tells me if the cuff is on properly or if I have rendered the reading inaccurate by moving or talking for example.
